Planetary Systems in Star Clusters

In the solar neighborhood, where the typical relaxation timescale is larger than the cosmic age, at least 10% to 15% of Sun-like stars have planetary systems with Jupiter-mass planets. In contrast, dense star clusters, charactered by frequent close encounters, have been found to host very few planets.

We carry out numerical simulations with different initial conditions to investigate the dynamical stability of planetary systems in star cluster environments.
